The contact owns a 2021 Toyota Corolla. The contact discovered brake fluid on the clutch pedal, and the brake pedal was mushy while depressed. The vehicle was taken to the dealer, who determined that the brake master cylinder needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 89,900.

At approximately 5 years and 2 months of ownership, with approximately 53,000 miles, the clutch slave cylinder failed in such a way that contaminated both the clutch and flywheel with brake fluid. Repair of this issue requires replacement of the slave cylinder, clutch, and flywheel, as described by Toyota of Pullman in Pullman, WA who performed the inspection and quoted the repair. The symptoms of this failure included an inability to shift the manual transmission between gears, most notably out of 1st gear to get to 2nd. This inability to change gears resulted in limited speed in traffic, and created an obstruction. In less fortunate traffic conditions, this speed restriction could have created a collision. Other owners of the same model vehicle online have reported active failures in traffic, some of which have resulted in damage to the transmission as well as the clutch and flywheel. Toyota appears to have redesigned the slave cylinder at least twice, implying that they know the par

“Engine Maintenance Required, See your dealer” light comes on the dashboard with a warning bell. Did a diagnostic test, and the code is the coolant bypass valve malfunction. This seems to be a common issue among 2020-2021 models. This has been inspected by professional mechanics.

NOTE: This has not happened to me yet, but it appears that most Corollas manufactured before 2022 or 2023 have this issue. However I did recently flush the fluid from my clutch system and it was very clearly contaminated, possibly indicating early evidence of a failure. Clutch system, specifically the slave cylinder is faulty on these vehicles. It is a known issue on these cars that the clutch slave cylinder (inside the transmission) is made out of resin and fails. When the slave cylinder fails, brake fluid from the shared clutch/brake reservoir leaks out onto the clutch and flywheel, damaging them and resulting in an expensive repair. In addition to this, the brake fluid leak results in a "low braking power" message on the dashboard, indicating a problem with the braking system. Obviously this is a safety issue that could cause an accident. This issue has been confirmed by many dealers and the solution is to replace the slave, clutch, and flywheel and flush & refill the brake fluid

On December 12, 2025, I was in a head on car accident in my 2021 Toyota Corolla nightshade. I was slammed into the steering wheel which caused injury. My car has over $14,000 worth of damage to the front yet my airbags did not deploy. I have taken my car to Toyota several times over the past few years and every time I’ve asked about a remedy for this recall I’ve been told there is no remedy as early as June or July 2025 I had to bring my car in for a manufacturer defect with the engine that Toyota fixed for free. I asked them about the recall on the airbags. They again told me there was no remedy.

The contact owns a 2021 Toyota Corolla. The contact stated that while driving in a parking lot, the clutch pedal failed to function as intended. The clutch pedal was depressed and failed to return after being released. The contact used his foot to raise the clutch pedal. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the slave cylinder had failed. The vehicle remained at the dealer unrepaired. Upon further investigation, the contact related the failure to the six-speed manual transmission. The manufacturer was notified of the failure and assisted with the labor cost. The failure mileage was approximately 58,000.

I am filing this complaint regarding a serious defect in my 2021 Toyota Corolla (Manual). At approximately 42,000 miles, the clutch slave cylinder failed. This defect caused hydraulic fluid to leak and contaminate the clutch assembly, resulting in significant damage and loss of proper function. Despite the fact that this issue stems from a defective part, the dealership has refused to cover the repair of the clutch assembly, stating that the clutch is not covered under warranty. Instead, they are requiring me to pay for the repair out-of-pocket, which would not have been necessary if the damage had not been caused by the defective clutch slave cylinder. I believe this is unfair and unsafe, as the failure of a clutch slave cylinder directly impacts the drivability and safety of the vehicle. This is a significant safety issue. A defective clutch slave cylinder can lead to sudden clutch failure, loss of vehicle control, and increased risk of accidents. This is not a wear-and-tear issue

While attempting to change a flat tire on a 2021 Toyota Corolla Hatchback, two wheel studs sheared off completely, leaving the wheel unsafe to drive. My wife was stranded alone in the mountains with no cell service. She managed to loosen three lug nuts, but the final two were seized. When a passerby assisted, both seized studs snapped. The spare could barely be mounted. The vehicle has been serviced exclusively by Toyota dealers since new. Lancaster Toyota later replaced the broken studs free of charge, yet simultaneously claimed that another dealer, Frontier Toyota, had “switched the tyres.” so Lancaster are not responsible. That claim is false — Frontier’s invoice (Sept 25 2025) clearly shows only an oil change and inspection, no tire or wheel service of any kind. Replacing the studs at no charge while denying responsibility suggests an attempt to quietly resolve what may be a dealer-induced over-torque or defective-stud failure. The broken studs were not returned to us des

The problem of windshield wipers going off either once, or at varying speeds has not been able to be reproduced by my Toyota dealership. It goes off right when I turn the car on 50% of the time and is very inconsistent. Wipers typically go off after using the turn signal, making long turns (such as into a parking spot), and driving on long curved roadways. It has been inspected and nothing has been found. There are no warning lights or messages.

I am filing this complaint regarding an unresolved safety recall affecting my 2021 Toyota Corolla. The recall involves the airbag ECU and has rendered the vehicle ineligible for rental on platforms like Turo. I purchased this vehicle specifically for rental income, and the recall has prevented me from listing it for over 14 months. Toyota has acknowledged the recall but has not provided a remedy or timeline for resolution. Their response offered no compensation or alternative solution. Based on comparable Turo listings in Frisco, Texas, I estimate monthly rental income of $810–$1,050, resulting in total lost income of approximately $11,340 to $14,700. I am requesting that NHTSA investigate the delay in remedy and consider enforcement action to ensure timely resolution and accountability.
